@ Eric: Yes I forgot to mention that cost (in addition to price) also
determines the profitability of mining and thus the total hashpower. I
disagree with your assessment of merge mining as really what matters
is opportunity cost of honestly mining vs attacking, and one reason we
are currently safe

In general, a target hashrate can be set by users (can be less or more
than the peak hash
The 51% problem is deep. Any discussion of a solution to it should
begin with a link to an article that shows a profound discovery has
been made. Selfish mining prevention and pollution should be on
bitcoin-discussion, but it appears that list is not active.
The problem with Andrew's idea below is
> Once hashrate gets large enough, no new miners (additional
hashrate) will want to join since their share of the hashrate is too
small to make a profit.
The share (hash power) of a miner is proportional to capital investment, not
the newness of that investment. The efficiency of a new mine (incl

Proof of memory (space) is just proof of work with extra steps. It does not
reduce energy consumption.

Interesting proposal though it introduces some elements

something needs to be explained about how this would not create an

Thank you, and my apologies. I should have sent that link just to you and

You might be interested in an idea I wrote about that is in a similar

The attacks I'm interested in preventing are not only selfish mining
and collusion, but also more subtle attacks like block withholding,
and in general anything that aims to drive out the competition in
order t
As I understand, selfish mining is an attack where miners collude to
mine at a lower hashrate then with all miners working independently.
What are the current strategies used to prevent this and what are the
future plans?
One idea I have is to let the block reward get "modulated" according
